To all whom it may concern:

Be it known thatl, Louis MAY, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful improvements in Pencil-Holders, of which the following is a specification.

My invention relates to pencil holders and particularly to one wherein gripping jaws are adapted to be engaged with the stub portion of a pencil, means being employed for movement on the jaws to move them into gripping action with the stub of the pencil to hold it accurately positioned.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several viewsz-Figure l is a side elevation of my limproved pencil holder, the clamping jaws being shown in their expanded positions. Fig. 2 is a sectional elevation of the pencil holder showing the clamping sleeve engaged with the gripping jaws to move them toward each other.

My improved pencil holder consists of a hollow inner tubular member 1 and a sleeve 2, the latter being mounted onthe former to slide thereon longitudinally. The member l at its outer end is split longitudinally to provide a pairof spring gripping jaws 3, each being formed intermediate of its length with a bulge 4. These bulged portions of the jaws are so constructed that they are provided with stop shoulders 5 for a purpose to be hereinafter described.

The sleeve 2 is formed with an enlarged portion 6 and with a contracted portion 7 which are so connected with each other as to form a stop shoulder 8 which is adapted to be engaged by the stop shoulders 5 on the bulged portions 4 of the gripping jaws to limit the sliding movement of the sleeve in one direction. It will be seen that the walls of the enlarged portion 6 of the sleeve are spaced from the walls of the tubular member and that the walls of the contracted portion 7 are engaged with the walls of the tubular member. rllhis construction is such that the sleeve can be moved on the tubular member with very little friction between it and the said tubular member. To limit the sliding movement of the sleeve in an opposite direction the member l is formed at its inner end with a collar 9 which is adapted to be engaged by the sleeve as shown in Fig. l of the drawing. The sleeve 6 is r0- vided with a hook 10 which, when the' ho der is inserted in the pocket, is adapted for clamping engagement with the outer wall of the pocket to hold the holder against loss.

The interior walls of the portion 6 of the sleeve are adapted for frictional engagement with the bulged portions 4 of the gripping jaws as shown in Fig. 2 of the drawing so that the said gripping jaws can be moved toward each other to lie approximately in parallel relation. When the sleeve 2 of the holder is moved to assume the position shown in Fig. l the gripping jaws will tend to separate from each other and the worn pencil or stub may be discharged and a new stub substituted therefor and the sleeve 2 again moved into gripping engagement with the jaws.

lt claim A pencil holder comprising a hollow tubular member, said member lbeing split longitudinally to provide gripping jaws adapted for clamping engagement with the pencil, each jaw being formed intermediate of its length with a bulged portion which is formed at its inner end to provide a shoulder, a sleeve mounted to slide on the tubular member and provided with an enlarged portion whose walls are spaced from the walls of the said tubular member and provided with a contracted portion whose walls are engaged with the walls of thetubillar member, said enlarged and reduced portions of the sleeve being connected together by a shoulder which is adapted to be engaged by the shoulders of the bulged portions of the jaws to limit the sliding movement of the sleeve in one direction, the said tubular member having a collar formed thereon at its opposite end to engage the sleeve to limit the sliding movement thereof in an opposite direction, the enlarged portion of 'the said sleeve being constructed whereby its inner walls may be engaged with the outer surfaces of the bulged portions of the gripping jaws to move the jaws toward each other and into clamping engagement with the pencil.

lln testimony whereof l aiiix my signature in presence o'l two witnesses.
